There are usually no "patches" or "updates" for the vCenter Server. You always download the same full vCenter image. When you start the installer, it detects that your system already contains a versions of the vCenter and does an update. If it does not find anything, it does a fresh installation. If it finds the same version, it goes into "Remove/Repair" mode.
